Main Capital IX is more than double the size of its predecessor, Main Capital VIII, which raised €1.9 billion in 2024 . Main Foundation III also more than doubled the previous foundation vehicle
.
The raise lifts Main's assets under management to over €12 billion. The firm now invests on behalf of over 200 limited partners .
New expansion into the United Kingdom: The firm announced plans to enter the UK market with these new funds .
Exclusive sector focus: Enterprise software (B2B) only. Main targets SaaS, cybersecurity, digital health, fintech, legal tech, govtech, and HR/payroll software . The firm pursues a buy-and-build strategy — acquiring majority and controlling stakes in profitable B2B software companies. It does not do minority growth equity or venture-stage deals
.
Main is making a deliberate contrarian bet. The firm's view, as reported by TNW and other outlets, is that while public markets fear AI will disrupt enterprise software, AI is instead creating a new frontier of growth for essential, 'boring' enterprise software .
According to Main, AI is rapidly reshaping how software is built, sold, and scaled, creating AI-driven growth opportunities across its core verticals — healthtech, govtech, infrastructure software, and others . The firm published a whitepaper titled "Why Enterprise Software Is Well‑Positioned to Capitalize on a New Phase of AI‑Driven Growth" and uses a proprietary AI Impact Assessment Framework

Charly Zwemstra, who founded the firm in 2003 and serves as its Managing Partner and Chief Investment Officer, framed the fundraise around several core ideas:
| Parameter | Detail |

| Fund names | Main Capital IX (€4.0B), Main Foundation III (€1.25B) |
| Combined size | €5.25 billion (~$6B) |
| Total AUM | > €12 billion |
| Re-up rate | > 120% |
| Exits / avg. return | 38 exits at 3.6x gross |
| Sector | B2B enterprise software only (buy-and-build) |
| Geographies | Benelux, DACH, Nordics, France, US, UK (new) |
| Ticket size | €5M–€150M per investment |
| Target EV | €30M–€500M per company |
| AI thesis | Contrarian: AI drives growth for 'boring' core software |
The announcement underscores a key moment for European private equity: a specialist firm with a narrow, repeatable thesis raised record capital from a global LP base by betting that the most valuable technology investments are not the flashiest, but the most essential.
